Electromagnetic valve streamline development direction of the road

Streamline the development direction of electromagnetic valve solenoid valves simplify development of hubei road online say is the time ( A) Simplify the control circuit is used in great quantities in the previous actuator pneumatic and electric control circuit, which increase the complexity of the system, while straight-pilot solenoid valves in the valve formation using control circuit of working medium itself, structure is simple. At home and abroad in the past, electromagnetic valve, a number of technical parameters also restricted now has extended to Omm domestic electromagnetic valve size; Low to medium temperature ℃, high to ℃; Work pressure from vacuum to MPa. Action time from 10 seconds to a few milliseconds. The new development of these technologies has been completely can replace original bulky expensive two quick cut-off valve and pneumatic control switch valve, electric switch valve, also can partly replace the continuous adjustment of pneumatic, electric control valve. ( 2) Simplified piping system automatic control valve to work on the tube road must also with some auxiliary valve and pipe fittings. In the front of the automatic control valve should be equipped with filters. Used in combination with multiple control valve also often need to install the check valve to prevent interference between the pipes. Now, one way solenoid valve, solenoid valve and solenoid valve with filtering have played a role in simplifying piping. ( 3) Simplify the structure of the valve and process solenoid valve belongs to the principle and structure are simple automatic control valve, but also further simplified. Home appliance industry washing machine, refrigerator with the electromagnetic valve, its parts structure and technology are suitable for mass production. Ordinary solenoid coil components, plastic package has been adopted to reduce lead fracture failure, at the same time easy to achieve the waterproof, explosion-proof protection requirement. The valve body, bonnet and other parts have been using precision casting, forging process, such as engineering plastics electromagnetic valve has batch on the market. Domestic explosion-proof solenoid valve has not only the flameproof, encapsulation type, and the Ann model. High pressure and high temperature of the solenoid valve is a simplified structure and process.
